Based on recent results on quasi-exactly solvable Schrodinger equations, we review a new phenomenological potential class lately reported. In the present paper, we consider the quantum differential equations resulting from position-dependent mass (PDM) particles. We first focus on the PDM version of the hyperbolic potential V(x) = asech2x + bsech4x, which we address analytically with no restrictioon the parameters and the energies. This is the celebrated Manning potential, a double-well widely… 
The exact solution of the Schrödinger equation with a polynomially spatially varying mass

Position-dependent effective masses in semiconductor theory. II.
It is shown that the customary derivation of position-dependent effective-mass Hamiltonians is by no means unique, and that there exist, in general, many nonequivalent Hamiltonians within the same approximation, all derivable from the basic many-body Hamiltonian.
